Senior Software Engineer, Inventory Performance

Quantcast is a large scale, data driven organization that lives and breathes data, processing well over 2 million transactions a second. Quantcast engineers leverage our large datasets, computational power and analytic tools to build high quality and diverse products that support Quantcast’s position as a world-class leader in online advertising.
 
The Inventory Performance team’s mission is two-fold: to drive improved performance for advertisers by delivering relevant advertising across the digital advertising ecosystem and to build defenses in order to protect our clients against fraudsters trying to siphon money out of the advertising space.  We are looking for top-tier talent with strong engineering and big data experience to help lead our efforts in designing, implementing and operating large scale ML systems in a production environment.

  • Collaborate with other engineers and work on a variety of large scale systems including our MapReduce cluster and global real-time bidding system
  • Develop techniques to efficiently extract meaning from petabytes of data, either to model suspicious online behavior to track down botnets and other fraudsters, or to understand and describe the interests and trends of the online community
  • Improve existing ad targeting and/or anti-fraud products and introduce new end-to-end products to delight our customers
  • Interface with Product & Business Operations teams to translate business requirements into robust and scalable solutions
  • Participate in on-call rotation supporting key products developed by the team

Requirements

  • B.S. in Computer Science or related technical field with 3+ years experience with high volume data processing; preferably in the online space
